It will ask you to choose a directory in which
to install the tcl/tk software.
You must install it in a new
folder named Tcl on the C partition, i.e.,

C:\Tcl

Create another installation folder, named C:\tk545.
It will be used for the
tk545 program and data files.

Download the zipped version of
tk545,
tk545-14.zip
into the C:\tk545 folder you created earlier.

Unzip the file into
the C:\tk545 folder after downloading it.
(Note to Windows XP users: Be careful to extract the
zip file into the correct folder.
Windows XP defaults to the wrong folder and
you must explicitly choose the correct folder.)

Remove the tk545.ini configuration file
if you have one left over from a previous installation.

You must reboot Windows before using tk545 for the
first time.

To start tk545, run the C:\tk545\tk545.bat batch file.

Notes

This installation procedure changed and
is now the same for Windows XP, Windows 98, and Windows ME.
The older instructions required editing the autoexec.bat
file, a file not used in Windows XP.

If you create a shortcut to C:\tk545\tk545.bat,
the shortcut works best if it is set up to run minimized
and close on exit.

Power your NRD-545 receiver on before starting
tk545
or else the program will freeze.
